diabetic 180A "worryingly high" number of children with type 1 diabetes show early markers of eye, heart and kidney disease according to a new report by the Royal College of Paediatrics and Child Health (RCPCH).

Data from England and Wales suggests more than 1,000 new cases of type 1 diabetes were recorded in people under-25 last year but overall blood sugar control in this group has improved, the study found.

Barbara Young, Diabetes UK chief executive, said there was evidence that children were experiencing problems with their eyesight or kidneys before they reached their 18th birthday.

She said: "This is tragic and we have great concerns for their future health if they are already showing signs of complications at such a young age. There is an urgent need for the NHS to make the pace of improvement quicker."

The RCPCH report showed that 26,867 children and young people with diabetes were recorded last year, compared with 25,221 in 2012/13. Yet just 16% underwent all seven annual health checks that are recommended to monitor their blood sugar control and any complications.

The figures further suggest that:
- More than 27% of young people had high BLOOD PRESSURE - putting them at risk of heart disease
- Some 7% had markers of future kidney disease
- Over 14% had early signs of eye disease - putting them at risk of blindness in later years
- More than 25% were classed as obese.

Dr Justin Warner, of the RCPCH, said: "This is the first time we have been able to collect and analyse the data on early warning signs and levels are higher than we would expect.

"There is some good news though - we can see from the audit that blood sugar control is getting better across England and Wales. We hope this will have a knock-on effect, reducing these early warning signs too."

Type 1 diabetes often appears in childhood and is caused by the immune system destroying cells in the pancreas, leaving patients unable to control their blood sugar.
